20100232042 | Lens driving device - In the present invention, a lens driving device has appropriate offset for miniaturization, excellent linearity of driving current versus displacement, and good displacement sensitivity. A casing holding a yoke with at least one permanent magnet mounted on an inner circumference thereof is connected with a lens holder having a driving coil installed on an outer sidewall thereof between an upper spring member and a lower spring member. When the driving coil is not powered, the lens holder props against the casing at a side opposite to an imaged object. When the lens holder props against the casing, the position of the driving coil along Z axis causing a magnitude of driving magnetic field intersecting with the driving coil is 50%˜90% of a maximum value of the driving magnetic field intersecting with the driving coil while the lens holder moves toward the imaged object. | 09-16-2010 |

20120300088 | Electromagnetically Driven Device - This invention provides an electromagnetically driven device applicable to a lens driving device with an anti-shake function by a simple structure that enables the movable member to swing around an axis thereof. A flat spring for swinging connects to a stationary frame body provided with a permanent magnet set and a coil set for swinging is mounted on an outer circumference of a movable frame body. When an axial direction of the movable frame body is designated as the Z axis, the coil set for swinging including a first through fourth coils arranged around the Z axis and spaced at uniform intervals with each winding around an axis perpendicular to the Z axis and opposite to the permanent magnet set respectively. The permanent magnet set includes a first through fourth magnets, wherein each magnet is arranged between two adjacent coils among the first through fourth coils. | 11-29-2012 |
20140376090 | LENS DRIVING DEVICE WITH IMAGE STABLILIZER FUNCTION - The present invention provides a lens driving device with image stabilizer function with high driving efficiency of second coils for swinging the lens, and the swing part is light. A lens support accommodating the first coil wound around the Z axis, and a base are respectively connected with first spring components extending along the direction perpendicular to the Z direction. The second coils are wound around the X direction and the Y direction and configured on the outer side of the first coil. A lens carrier and a carrier bracket provided with the second coils are connected with the second spring component extending along the Z direction. The second spring component is supported by the lens carrier and can swing in the X direction and the Y direction. | 12-25-2014 |
20150036231 | LENS DRIVING DEVICE - The present invention provides a lens driving device includes at least two spring components each of which includes an inner side retaining part, an outer side retaining part, a plurality of wrist parts configured between the inner and outer side retaining parts and prolonged along the circumference direction, inner side connecting parts for connecting one ends of the wrist parts with the inner side connecting part, and outer side connecting parts for connecting the other ends of the wrist parts with the outer side retaining part. Moreover, serpentine necking parts are formed at the roots of the connecting part of the inner side retaining part, straight line-shaped necking parts are formed at the roots of the connecting part of the outer side retaining part, so that stresses acting on the inner side connecting parts and the outer side connecting parts during assembling are absorbed. | 02-05-2015 |
